For example: We know the HTML element we are dealing with is
always an <a> element.
I believe the small changes in this patch are all obvious and
non-controversial. Please let me know if you disagree.

We added reference preview as a checkbox the the
anonymous user settings. To handle both popup types
(pages and references), we changed the usage of
preview.enabled. We pass on all types as a map
inside preview.enabled. The footer link to edit the

one type is disabled.

The main motivation here is to dramatically reduce the number
of places that use the same property name "enabled" for values
on different objects (e.g. "state", "actions", and "updates"
are all different things) with slightly different meanings. I
tried hard to come up with names that reflect better what each
meaning is.

Reduce layout/style thrashing by measuring all required geometries
at event handler, not waiting for delays/redux/style changes.
Use CSS bottom instead of top, to avoid having to measure the popup

Disable some test cases that relied on implementation detail of using
"top" CSS.

Change-Id: I2fe92579574b3b1ba4d2dd064899eee944045a96
I was able to track the issue down to the changes made in this patch:
https://gerrit.wikimedia.org/r/331563
This patch is mostly a simplification of ce8a2d4
(I9a73b3086fc8fb0edd897a347b5497d5362e20ef):
- Don't make wait#wait() abortable. This adds complexity and isn't
needed since the token is rechecked in the .then() of
actions#linkDwell(). The request is permitted to continue and fetch if
that token still matches and is never issued otherwise.
Once a request has been issued, that request is still abortable.
However, note that calling XHR.abort() is just a request to abort and
may not be granted. Whether or not XHR.catch() is invoked is what
dispatches the FETCH_ABORTED action (or doesn't if the request to
abort was denied).
- Remove the abort tests for wait#wait() since the functionality is no
longer provided.
- Pass the preview token in the FETCH_ABORTED action and reduce
FETCH_ABORTED the same way as ABANDON_COMPLETE in reducers/preview.
The follow-up patch, I3597b8025f7a12db0cf5d83cce5a77abace9bae3, adds
integration tests for the specific bug fix. Note that these Selenium
tests are incompatible with the content proxy, so it is probably best to
simply unset $wgPopupsRestGatewayEndpoint and $wgPopupsGateway and allow
the defaults to be used. Also note that the tests are incompatible with
recent versions of Node.js (so use NVM) and emit many deprecation
warnings (so set deprecationWarnings to false in
tests/selenium/wdio.conf.js) An example run of the tests looks something
like:
chromedriver --url-base=wd/hub --port=4444 &
# If any changes are made locally, also run `npm -s start &`.
MW_SERVER=http://localhost:8181 \
MEDIAWIKI_USER=foo \
MEDIAWIKI_PASSWORD=bar \
DISPLAY= \
npm -s run selenium-test
Live testing may be performed as well. Remember that RESTBase requests
are incompatible with MobileFrontend's content proxy hack so ensure to
comment it out if $wgPopupsGateway is configured for RESTBase (see
T218159).
1. Open the DevTools network tab.
2. Disable the browser cache. Chromium, at least, won't abort requests
coming form the cache.
3. Hover back and forth quickly over a preview. In Chromium, canceled
requests are labeled and appear red. This is a good scenario to test.
With the patch, a preview should always be shown when ultimately
resting on a link. Without the patch, it is possible to rest upon the
link with no preview showing. This may require several attempts.

Introducing the REFERENCE_CLICK action that will fetch and show the
preview for the clicked reference right away without any delay.
The main goal of the new chain of events introduced with the reference
click is showing the reference preview right away. The actions triggered
by the dwelling include delays in multiple parts of the process.
If there's a dwell action-chain in progress when the click action is
executed, the related promise ( that might still include steps with
delays ) and the reference preview is retrieved and shown right away
re-using the token.
In the case where there's no dwell action running ( e.g. when the click
was triggered via touch ) we create a new token and start from scratch.
In either case we want to avoid, that multiple clicks trigger multiple
actions and abort early when there's already a click action in progress.

It's not exclusively about page summaries any more.
We had a few suggestions in mind:
* get, fetch, request, or issueRequest. But I feel these are all to
generic and don't describe well what the method does. As a reminder:
It expects a Title object and returns a promise, which returns a
PreviewModel object, which contains an HTML "extract".
* fetchPreview? I feel this can still mean to many things.
* fetchPreviewModel? But we don't really need to repeat that it will
return a model object.
So I went for fetchPreviewForTitle. What do you think?

FETCH_COMPLETE_TARGET_DELAY is used to introduce an artificial delay to
HTTP requests as needed. However, FETCH_START_DELAY is always accounted
for so it makes sense to define FETCH_COMPLETE_TARGET_DELAY with it. The
docs are updated to draw the distinction between total delay and API
response delay.

Currently the Popups schema is disabled but if we were to re-enable
it, the page tokens would now be consistent with the ReadingDepth

The getToken function is kept to allow generation of the

* I've updated various tests to use the central mw.user stub to make
clearer where tokens come from.

Although Popups only uses JSDocs at this time which seemingly doesn't
care about casing[1], we should endeavor to use the proper return types.
This patch lowercases typing to indicate primitive / boxed type as
appropriate.[2] As a special case, function types are uppercased for
compatibility with TypeScript type checking.
Lastly, JQuery types are of type "JQuery". The global JQuery object's
identifier is "jQuery". This patch uppercases J's where appropriate.

Whe user moves mouse away and we abort the http request we shouldn't
count that request as a FETCH_FAILED. The reasoning behind is that
FETCH_FAILED state increments the counter.PagePreviewsApiFailure.
Our StatsD graph gets polluted with lots of aborted requests and it
becomes unsuable. It doesn't show only the failed requests.
Changes:
- introduced new state: FETCH_ABORTED
- switch to FETCH_ABORTED when browser aborts the request

Previous implementation did not pass the `result` variable
to the catch() statement. Because of that every execution that
ended with exception inside fetch() statement was threated as
not a network exception and tried to present the null preview.
Changes:
- properly handle data returned by rejected fetch promise
- chaged the big if (result && result....) into something easier
to read
- pass Error object instead of 'http' string
- Restbase can return exception, it doesn't have to handle the 404
errors by itself, it's already taken care in the catch() logic
- fixed unit tests to reflect new logic in restbase gateway

Whenever an HTTP request sequence is started, i.e. wait for the fetch
start time, issue a network request, and return the result, abort the
process if the results are known to no longer be needed. This occurs
when a user has dwelt upon one link and then abandoned it either during
the fetch start wait time or during the fetch network request itself.
This change is accomplished by preserving the pending promises in two
actions, LINK_DWELL and FETCH_START, and whenever the ABANDON_START
action is issued, it now aborts any previously pending XHR-like promise,
called a "AbortPromise" which is just a thenable with an abort() method.
There is a similar concept in Core:
ecc812f06e/resources/src/mediawiki.api/index.js.
Aborting pending requests has big implications for client and server
logging as requests are quickly canceled, especially on slower
connections. These differences can be observed on the network tab of
DevTools and the log in Redux DevTools.
Consider, for instance, the scenario of dwelling upon and quickly
abandoning a single link prior to this patch:
BOOT EVENT_LOGGED LINK_DWELL FETCH_START ABANDON_START FETCH_END STATSV_LOGGED ABANDON_END EVENT_LOGGED FETCH_COMPLETE
And after this patch when the fetch timer is canceled (prior to an
actual network request):
BOOT EVENT_LOGGED LINK_DWELL ABANDON_START ABANDON_END EVENT_LOGGED
In the above sequence, FETCH_* and STATSV_LOGGED actions never occur.
And after this patch when the network request itself is canceled:
BOOT EVENT_LOGGED LINK_DWELL FETCH_START ABANDON_START FETCH_FAILED STATSV_LOGGED FETCH_COMPLETE ABANDON_END EVENT_LOGGED
FETCH_FAILED occurs intentionally, STATSV_LOGGED and FETCH_COMPLETE
still happen even though the fetch didn't complete successfully, and
FETCH_END doesn't.
Additionally, since less data is transmitted, it's possible that the
timing and success rate of logging will improve on low bandwidth
connections.
Also, this patch tries to revise the JSDocs where possible to support
type checking and fix a call to the missing assert.fail() function in
changeListener.test.js.

* New action added PREVIEW_SEEN
* The action will be used to signal that a page view needs
to be recorded.
* PREVIEW_SEEN is a delayed action which is triggered
as a side-effect of the previewShow action. It is only dispatched
if the user is still previewing the same card and the page
related to the card has preview type `page`
* The pageview changelistener is added when
$wgPopupsVirtualPageViews is set to true.
* The page view changelistener listens for page views and logs
them using EventLogging when needed using
https://meta.wikimedia.org/wiki/Schema:VirtualPageView
Note:
* Currently if a user has enabled the DNT header, the
event will not be logged. There is ongoing discussion on the
ticket and fixing this will be addressed separately.
* Only title and referrer are logged in the initial version.
The task demands that "namespace" is logged but this information
is not provided by the summary endpoints we use so will need
to be added later (if indeed needed) either via a change to that
endpoint of by using JavaScript to parse the URL.

This change fixes some issues with assertions not running, removes
unnecessary promise dances, and improves legibility and some code
patterns in the action and integration node tests mainly.
Detailed changes:
* actions.js
* Fully migrate out of jQuery 1 promises (no done/fail)
* Fix linkDwell action not returning the fetch action promise
* actions.test.js
* Simplify setupWait for the tests
* It always autoresolves immediately the wait call to ensure speedy tests
* No waitDeferreds or waitPromises array coordination, rely on action
returned promises instead
* Get rid of that = this in favor of arrow functions
* Rename generic "p" promises to meaningful names
* Add assert.expect for more solid tests (so that we don't skip assertions in
the future if we change them)
* Fix some assertions that weren't being run because of the incorrect promise
being returned (p.then, and then just returning p)
* Get rid of $.when stubbing in favor of waiting for the promise returned from
the action
* Get rid of hacky setTimeout(..., 0) to run assertions after the promises
* integration.test.js
* Get rid of wait(0) calls to hack around asynchronous actions
* Use the action returned promises instead of the waitPromises/Deferreds
* Remove unused "el" parameter being passed to this.abandon in several tests
* Remove unnecessary test helper this.abandonPreview (it was the same as
this.abandon)

Functional changes
- Show the default / error preview for all extract request failures
except those due to network circumstances (such as CORS) or no
connectivity (offline). Previously, the error preview was displayed
only for missing pages.
- FETCH_COMPLETE was previously only dispatched after FETCH_END. Now
it's also dispatched after FETCH_FAILED. The additional "fetch
complete" is not expected to impact logging. The states of success
are: START, END, COMPLETE. The new failure states are consistent with
success: START, FAILED, COMPLETE.
Testing
Errors may be stimulated in a number of ways including:
- Timeout: add a timeout field to RESTBaseGateway /
MediaWikiGateway.fetch().
http://api.jquery.com/jquery.ajax/
- Bad request: change MediaWikiGateway.fetch's action field to
`Math.random() > 0.5 ? 'query' : 'fail'` and RESTBaseGateway.fetch's
url field to
`RESTBASE_ENDPOINT + ( Math.random() > 0.5 ? encodeURIComponent( title ) : '%%%' )`.
- Desired Gateway can be configured in Gateway#createGateway().
- Note: T184534 describes a circumstance where cached previews may not
appear when offline. Disable browser caching to avoid confusion.

Instead of using the non-standard old Promise implementation by relying
on .fail, migrate it to .catch.
In this specific case, where we were chaining promises with $.when, the
semantics from going from fail to catch actually change. .fail keeps the
promise in a rejected state, while .catch will change it to resolved
unless another error is thrown.
As such, when changing it to .catch, the catched error will be re-thrown
to keep the promise in a rejected state, so that $.when.then is not
executed.

* Make actions.js#fetch return its promise for ease of testing.

Given that interactions end up with an event logged, there shouldn't be
a reason to keep an interaction active after it's corresponding final
event has been logged. See Tbayer's state graph.
This patch removes the current interaction if an event with that token
is logged, effectively finalizing it and making it impossible for the
token to be reused from the state tree again.
Additional changes:
* Pass the logged event with the action EVENT_LOGGED so that the reducer
can determine if it needs to do anything else.
* Since the interaction is removed, when undefined, guard against
actions that use state.interaction freely. (Only allow BOOT,
LINK_PREVIEW, and EVENT_LOGGED)
